Muaem'mer ibn Khal'lad narrated that he told Imam Reza (a.s): “Should I pray for my parents who do not recognize God's religion?” Imam Reza (a.s) said
“Pray for them, give charity for them, and treat them kindly if they are alive and do not recognize God's religion, since the Prophet of God (a.s) said: God appointed me for mercy not disobedience.”
